Maltapyro Posted September 28, 2022 Posted September 28, 2022 KCLO3 /AL/ S is already a dangerous composition which should be screened very cautiously while monitoring temperature and humidity levels ,let alone pressing it. It will not make a very good salute, KCLO4 and AL is a better comp, however still dangerous.
mx5kevin Posted December 12, 2022 Posted December 12, 2022 KCLO3 /AL/ S is already a dangerous composition which should be screened very cautiously while monitoring temperature and humidity levels ,let alone pressing it. It will not make a very good salute, KCLO4 and AL is a better comp, however still dangerous. KClO4 Al with presence of sulfur (10% ideal) or Sb2S3 (10-15% ideal) based flash powders the only one what can give safe way extreme loud reports. Not the KClO4/Al 70:30 that is weak for the purpose. Or with often magnalium or less often the most reactive magnesium for much more faster and reactive comp with Sb2S3 or sulfur but these are more sensitive. This is the only real flash powder for high powered firecrackers. What can give the same power and sound absolute unsafe way are the KClO3. There is no other alternative to this. Other oxidizers are not strong enough for this. Chinese pro pyrotechnicians know this well. And in the EU no coincidence banned the 2 oxidizer for private users. Classic cigarette size Pirate firecrackers with maximum 0.5g flash and under 0.3g, 0.2g, and especially the mini Pirat with less than 0.1g flash it cannot be made in adequate quality without it. I have been researching this theme for more than 10 years. From all Nitrates, KMnO4, persulphates, BaSO4, NH4ClO4, Ba(ClO3)2, this performance cannot be approached. Many of these are not even used in the factory only some people using it at home. Especially at home, the amateurs use all kinds of FP, but this will never be the same. It's really a waste of time and money. There are no widely distributed accurate records of this in amateur circles, because even those who experiment draw wrong conclusions. The most powerful flash powders can be made from the most reactive metal, magnesium then comes the 50:50 magnalium and the less reactive aluminum. The raw material is of insufficient fineness, the ratio are wrong, the metal powder is not properly coated or protected, and the ingredients are not properly mixed either. This leads to incorrect conclusions. It takes several years of active practical experience to be able to draw correct conclusions. And there are very few people who have been doing it for many years. First have to learn to make it well a KNO3 Mg S flash powder. If this is not strong enough for someone, they will not find an alternative that is significantly stronger than this under KClO3 or KClO4. Only KMnO4 between the two in power which is useless and have zero storage stability. Coating the Mg correctly with linseed oil, drying the KNO3 and grinding it to extremely fine powder, and mixing calculating correctly the ingredients. The factory setup using it in larger firecrackers like 1.4g Nitrate Bangers. This is a strong and fast flash. If this doesn't work with this, KClO4 won't work either. Many people do not even understand the difference between magnesium and aluminum powder. How magnesium is a more reactive metal than aluminum. We prepare these raw materials for a product, every detail counts there. Those who do not have many years of experience make a lot of mistakes. People with mixed knowledge give advice on the Internet. This information is full of serious mistakes. There are very few people who do certain things artistically at a very professional level. KClO4 a much more stronger oxidizer than nitrates those who found the two to be similar in terms of performance do not have the appropriate experience. 1
L0k1 Posted June 11, 2023 Posted June 11, 2023 you should prob stop messing with flash powder before you get hurt flash should not be pressed and if you done any homework you would know that it needs to be loose and fluffy, seriously you should do alot of reading before messing with something that can delimb you or even death, I'm just glad he wasn't ramming it with a hammer....

I quickly noticed, you are a real professional in this topic with a lot of practical experience and I also have read your Website, with auto translation from hungarian, what was full of translation-mistakes, but anyway still readable. Good information, I learned something too, even while it was all mixed together in one site, what was a bit bad, for overview. But I appreciate your sharing of knowledge and practical experiences.
DavidF Posted March 9 Posted March 9 The forum rules say that this topic is discouraged, but can be discussed intelligently. The recent effort to lock and re-locate all threads referring to flash is going to take quite a lot of effort, since we are all so used to being able to speak somewhat freely here. The moderator has his work cut out for him! It's going to be like playing whackamole to keep shutting down discussions containing the 'F' word and re-locating them. There are many (maybe hundreds) of threads that will be affected by this new action. As members bring these old threads back up, it's going to take a daily effort to suppress them all, and to sequester all the other valuable, unrelated information contained in the offending threads. I'm glad I'm not the one that has taken on such a task!

I'm glad I'm not the one that has taken on such a task! Flash powder is one of the most popular pyrotechnic materials. I sense external interference on this topic, as if a 'rogue officer' is trying to remove these threads. However, if we can't discuss things openly, few of us will remain. Some people are greatly bothered when, instead of silly questions and conversations, we delve into more serious topics that help many assemble pyrotechnic devices more effectively.

The problem at hand is- Inexperienced folk can easily kill themselves and others. Ask to be included in the HE forum. You will be kinda vetted- as at least those in the know know yer not an idiot “Kewl” 13 year old. Well, I guess 23 or even 33

Pyro comps like flash powder and a real HE like TATP or HMTD should not be mistaken for one another.
bugmenot1 Posted March 14 Posted March 14 An experienced person should share information with a beginner to the best of their knowledge, and at that point, they have done everything to ensure safety and quality. Making a ground salute or a firecracker is not the most dangerous because there is no pressing involved. If incompatible materials are not used, making flash powder is not particularly dangerous either. However, a fountain with stars or rockets involves pressing, and during the pressing process, the risk of an unexpected explosion is much higher. One can recall the Rouge Science E&W forum, where everything was openly discussed. There is no consideration here for the interests of beginner youths. The embedded authority figures have an appetite that is too large. They are not concerned with the safety of beginners, only with removing pyrotechnic materials. The more we yield to them, the bigger their appetite will become. This represents the greatest danger to both beginners and the entire community. If anything needs to be removed, it’s these embedded authorities, whose only role here is to destroy the community and engage in espionage.
